Web Page

Web Page
i was just wondering if Java could open a web page like www[dot]google[dot]com
in swing:
say a button is clicked(actionperformed),
//....
//I want the command here.
I even want to close the page after sometime(not manually).
How can I do so?
Thank You.

Not my own code, but I've used this class before:

/////////////////////////////////////////////////////////
//  Bare Bones Browser Launch                         //
/////////////////////////////////////////////////////////

import java.lang.reflect.Method;
import javax.swing.JOptionPane;

public class BareBonesBrowserLaunch {

   private static final String errMsg = "Error attempting to launch web browser";

   public static void openURL(String url) {
      String osName = System.getProperty("os.name");
      try {
         if (osName.startsWith("Mac OS")) {
            Class fileMgr = Class.forName("com.apple.eio.FileManager");
            Method openURL = fileMgr.getDeclaredMethod("openURL",
               new Class[] {String.class});
            openURL.invoke(null, new Object[] {url});
            }
         else if (osName.startsWith("Windows"))
            Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + url);
         else { //assume Unix or Linux
            String[] browsers = {
               "firefox", "opera", "konqueror", "epiphany", "mozilla", "netscape" };
            String browser = null;
            for (int count = 0; count < browsers.length && browser == null; count++)
               if (Runtime.getRuntime().exec(
                     new String[] {"which", browsers[count]}).waitFor() == 0)
                  browser = browsers[count];
            if (browser == null)
               throw new Exception("Could not find web browser");
            else
               Runtime.getRuntime().exec(new String[] {browser, url});
            }
         }
      catch (Exception e) {
         JOptionPane.showMessageDialog(null, errMsg + ":\n" + e.getLocalizedMessage());
         }
      }

   }

To open a webpage:

BareBonesBrowserLaunch.openURL(urlStr);

but how to close?

but how to close?

What close are you talking about?

[coder_java_]

I am talking about closing the opened Web Browser through Java.
Like:
BareBonesBrowserLaunch.openURL(urlStr);
to open.
.................................
to close it after the page is loaded,or after some given time.
Thanks

You cannot close an application using Java. Actually you cannot open an application either. In that above code you don't have open an application(ie: browser). Confused? In reality what happen there is, that code segment simply telling that browser what's being sent, actually content of the browser. Then browser decide how to execute that. Nothing related or nothing to do with Java in that sense.

so in that sense,Java is not so powerful rite?
so I have no way to control applications?
It is possible so many popular softwares right?
so not even an experienced Software Engineer can do this?
Thanks for your help.

No lol, Java is more powerful to do this. To deal with application executions you have to learn about Process.
